With the progress and development of society,people have higher and higher requirements for food safety.As a new crop cultivation technology,pollution-free crop cultivation is one of the hotspots in the current agricultural technology research.The cultivation of pollution-free crops can not only provide a good growth environment,but also reduce the use of pesticides,which is conducive to the protection of the ecological environment and people's health.In the process of the implementation of pollution-free crop cultivation techniques,reasonable pest control measures need to be taken to improve crop quality.This paper analyzes the cultivation techniques of pollution-free crops,discusses the control measures of diseases and insect pests,and improves the cultivation technology level of pollution-free crops,so as to provide reference for the application and popularization of pollution-free crops in the future.
